BB1....your suggestion is very good.  I was in the hospital for six days and then home.  I am on Medicare and I had at home nurse visits, occupational therapy and physical therapy for several weeks. The physical therapist had me doing exercises and left me with ones to do.  The occupational therapist was fantastic helping us figure out how to do things and use my knee rover and other things.  This was all a huge help. Just so much you do not know how to do one one leg.
